TEKS Grade 8 Science - 8.9 Plate Tectonics

The model below shows two continental plates. The folded mountains in this model form at which type of plate boundary?

The thick black lines on the map below show the locations of mid-ocean ridges. Which geologic feature is most likely to form at a mid-ocean ridge?

The image shows a plate boundary. Arrows have been added to indicate the movement of the plates. What plate boundary feature is also shown?

The map below shows the locations of four active volcanoes in the Caribbean Sea. What do these volcanoes indicate about plate tectonics in the region?

The map shows some of Earth’s plate tectonic boundaries. Based on the map, volcanic activity would most likely be found at —

The diagram below shows a model of the movement of two tectonic plates. When the plates collide, one plate often moves below the other plate. The rising magma that can result from this type of plate movement may produce —

The Himalayan mountains are shown on the map below. Four students were asked to identify the geologic process that caused this mountain range to form. Their responses are shown below. Which student correctly identified the geologic process that formed the Himalayan mountains?

The San Andreas fault is a transform fault. The map below shows a student’s approximation of where the fault line crosses through the United States. Students were asked to make maps predicting which way land would most likely move over thousands of years. Which map best predicts the likely movement of land along the fault line over thousands of years?

A mid-ocean ridge separates the Pacific plate and the Nazca plate off the western coast of South America. Which statement best describes the relative motions of the Pacific and Nazca plates?
